BACKGROUND OF THE INVENTION

TNF-related apoptosis-inducing ligand (TRAIL; Apo2L) is an endogenous protein that selectively induces apoptosis in cancer cells. TRAIL is a powerful inducer of apoptosis in a wide range of human cancer cell lines via pro-apoptotic death receptor 4 (DR4; TRAIL-R1) and death receptor 5 (DR5; TRAIL-R2) at the cell surface through engagement of the extrinsic or intrinsic apoptotic pathways. TRAIL plays a direct role in tumor suppression during immune surveillance but this anti-tumor mechanism is lost during the disease progression. The ability of TRAIL to initiate apoptosis selectively in cancer cells has led to ongoing clinical trials with administration of recombinant TRAIL and the longer-lived TRAIL-agonist antibodies targeting either of its two pro-apoptotic death receptors.

Despite its potency, recombinant TRAIL has efficacy-limiting properties such as short serum half-life, stability, cost, and delivery. Delivery of recombinant TRAIL or TRAIL-agonist antibodies to the brain is limited by inability of recombinant TRAIL and TRAIL-agonist antibodies to cross the blood-brain barrier. Accordingly, there is a continuing need for anti-cancer compositions and methods.

In some embodiments, treatment of cancer comprises prevention of tumor growth in a cancer subject. In some embodiments, treatment of cancer comprises prevention of formation of cancer metastases in a cancer subject. In some embodiments, treatment of cancer comprises targeted treatment of minimal residual disease in a cancer subject known to have the minimal residual disease in a cancer or a subject at risk for having minimal residual disease.

This might be indicated after treatment of the primary tumor by surgery and/or after chemotherapy (e.g. radiotherapy) has been initiated or determined to efficacious. Disseminated tumor cells may be in their dormant state and often cannot be attacked by the chemotherapy (radiotherapy). A thus treated patient seemingly is in a healed state, which is also described as “minimal residual disease”. Nevertheless, the dormant tumor cells have a potential of forming metastases if they become metastasising cells due to a growth stimulus also after a longer dormant state.

As used herein, “minimal residual disease” denotes a small number of cancer cells that remain in in a subject during treatment, or after treatment when the subject is in remission (exhibiting no symptoms or signs of the disease). The methods described herein are preferably applied to any form of the diseases listed herein, including adult and childhood forms of these diseases.

In some embodiments of the method of treatment, the predetermined waiting time is determined by a quantitative assessment of renal function and parameters of renal. In some embodiments of the method of treatment, the predetermined waiting time is determined by an assays for the determination of renal function, wherein the assay is selected from the group consisting of serum level of compound (1) or the pharmaceutically acceptable salt thereof; compound (1) or the pharmaceutically acceptable salt thereof clearance rate; 24-hour urinary clearance of compound (1) or the pharmaceutically acceptable salt thereof or a metabolite thereof.

In one embodiment of the method of treatment, the predetermined waiting time substantially equals to the time required for systemic clearance of compound (1) or a pharmaceutically acceptable salt thereof from the body of the subject. In one embodiment of the method of treatment, the predetermined waiting time substantially equals to the time required for renal clearance of compound (1) or a pharmaceutically acceptable salt thereof from the body of the subject. In one embodiment of the method of treatment, the predetermined waiting time substantially equals to the time required for hepatic clearance of compound (1) or a pharmaceutically acceptable salt thereof from the body of the subject. In one embodiment of the method of treatment, the predetermined waiting time substantially equals to the time required for total clearance of compound (1) or a pharmaceutically acceptable salt thereof from the body of the subject. In one embodiment of the method of treatment, the predetermined waiting time is about 4 hours. In other embodiments the waiting time is 1 day. In some embodiments, the wait time is until C max of compound (1) has passed. In other embodiments, the waiting time is after most of the adverse events are resolved or are resolving. In one embodiment of the method of treatment, the predetermined waiting time is about 2 days. In one embodiment of the method of treatment, the predetermined waiting time is about 3 days. In one embodiment of the method of treatment, the predetermined waiting time is about 4 days. In one embodiment of the method of treatment, the predetermined waiting time is about 5 days. In one embodiment of the method of treatment, the predetermined waiting time is about 6 days. In one embodiment of the method of treatment, the predetermined waiting time is about 7 days. In one embodiment of the method of treatment, the predetermined waiting time is about 1-7 days. In one embodiment of the method of treatment, the predetermined waiting time is about 1-6 days. In one embodiment of the method of treatment, the predetermined waiting time is about 1-5 days. In one embodiment of the method of treatment, the predetermined waiting time is about 1-4 days. In one embodiment of the method of treatment, the predetermined waiting time is about 1-3 days. In one embodiment of the method of treatment, the predetermined waiting time is about 1 to 2 days. In some embodiments, the waiting time is up to 3 weeks. The preceeding are considered “therapeutic time periods.”

When the order of administration is reversed, timing for the administration of compound (1) can be after the C max of the first administered drug has passed. In some embodiments, administration of compound (1) can be after most or substantially all of the first administered drug has been eliminated from the body or the toxicity effects for the first administered drug are resolved or are resolving.

In some embodiments, the method of treatment further comprises monitoring level of compound (1), a pharmaceutically acceptable salt thereof, or a metabolite thereof in the subject using pharmacokinetic profiling.

In some embodiments of the method, which include monitoring level of compound (1), a pharmaceutically acceptable salt thereof, or a metabolite thereof in the subject using pharmacokinetic profiling, at least two samples are collected from the subject at point-of-care or point of use by sampling or self-sampling on point-of-care devices or point of use devices or on matrices suitable for storage of the at least two samples prior to quantitation in a laboratory. In some embodiments of the method of treatment, each of the point-of-care devices or point of use devices is capable of quantitating compound (1), a pharmaceutically acceptable salt thereof, or a metabolite. In some embodiments of the method, which include monitoring level of compound (1), a pharmaceutically acceptable salt thereof, or a metabolite thereof in the subject, one or more samples are collected from the subject at point-of-care or point of use by biopsy device for analysis at the point-of-care or point of use devices or for storage prior to analysis by a laboratory. In some embodiments of the method, a biopsy is taken after a time interval of 3-8 hours following administration of compound (1), a pharmaceutically acceptable salt thereof, or a metabolite thereof to the subject. In some embodiments of the method, a biopsy is taken after a time interval of 3-24 hours following administration of compound (1), a pharmaceutically acceptable salt thereof, or a metabolite thereof to the subject. In some embodiments of the method, a biopsy is taken after a time interval of 8-24 hours following administration of compound (1), a pharmaceutically acceptable salt thereof, or a metabolite thereof to the subject. In some embodiments of the method, a biopsy is taken after a time interval of 2 days following administration of compound (1), a pharmaceutically acceptable salt thereof, or a metabolite thereof to the subject. In some embodiments of the method, a biopsy is taken after a time interval of 3 days following administration of compound (1), a pharmaceutically acceptable salt thereof, or a metabolite thereof to the subject. In some embodiments of the method, a biopsy is taken after a time interval of 4 days following administration of compound (1), a pharmaceutically acceptable salt thereof, or a metabolite thereof to the subject. In some embodiments of the method, a biopsy is taken after a time interval of 1-7 days following administration of compound (1), a pharmaceutically acceptable salt thereof, or a metabolite thereof to the subject.
